Performance Verification
Performance Verification Procedures
Two types of Performance Verification procedures can be performed on this
product; Brief Procedures and Performance Tests. You may not need to perform
all of these procedures, depending on what you want to accomplish.
H To rapidly confirm that the analyzer functions properly and was adjusted
properly, do the brief procedures under Functional Tests and Diagnostics,
which begin on page 1–3.
Advantages: These procedures are quick to do, require no external
equipment or signal sources, and perform functional and accuracy testing to
provide high confidence that the analyzer will perform properly. They can be
used as a quick check before making a series of important measurements.
H If more extensive confirmation of performance is desired, do the Perfor-
mance Tests, beginning on page 1–9, after doing the Functional Tests and
Diagnostics just referenced.
Advantages: These procedures add direct checking of warranted specifications.
Disadvantages: They require more time to perform and suitable test
equipment is required. (Refer to Equipment Required on page 1–11.)

Procedure
H Each procedure consists of as many steps, substeps, and subparts as required
to do the test. Steps, substeps, and subparts are sequenced as follows:
1. First Step
a. First Substep
H First Subpart
H Second Subpart
b. Second Substep
2. Second Step
H Instructions for menu selection follow this format:
FRONT PANEL KEY Õ Side Menu Key Õ Submenu Key.
For example, “Press MODE: DEMOD Õ Digital Demod Õ Constellation”.
“MODE: DEMOD” indicates the DEMOD key in the MODE menu area on
the front panel.
H In steps and substeps, the lead-in statement in italics tells you what to do,
and the instructions that follow tell you how to do it.
The example step below is telling you to set the analyzer controls by
pressing the specified key sequence.

Brief Procedures
The Functional Tests use the internal calibration signal as a test-signal source for
further verifying that the analyzer functions properly.
The Diagnostics use internal routines to verify that the instrument functions
properly and passes the internal circuit tests.
The following section provides the details.

Performance Tests
This section contains procedures for checking that the RSA3408A 8 GHz
Real-Time Spectrum Analyzer performs as warranted.
The procedures are arranged in four logical groupings:
H Frequency Checks
H Noise Sideband Checks
H Amplitude Checks
H Spurious Response Checks
They check all the characteristics that are designated as checked in Chapter 2,
Specification. (The characteristics that are checked appear with the n symbol in
the Characteristics column in Chapter 2.) You can use the form at the end of this
section as a test record.
Read Performance Verification Procedures that start on page 1-1. Also, if you
are not familiar with operating this analyzer, read the RSA3408A User Manual
before doing any of these procedures.
STOP. These procedures extend the confidence level provided by the basic
procedures described on page 1–3. Perform the basic procedures first and then
perform the following procedures if desired.

Performance Tests
Prerequisites
The tests in this section make up an extensive, valid confirmation of performance
and functionality when the following requirements are met:
H The cabinet must be installed on the analyzer.
H The instrument must have passed the procedures under Brief Procedures
found on page 1–3.
H A signal-path compensation must have been done within the recommended
calibration interval and at a temperature within ±3 _C of the present
operating temperature. (If at the time you did the prerequisite Brief Proce-
dures, the temperature was within the limits just stated, consider this
prerequisite met.)
H The analyzer must have been last adjusted at an ambient temperature
between +20 _C and +30 _C, must have been operating for a warm-up
period of at least 20 minutes, and must be operating at an ambient temperature of between +10 _C and +40 _C. (The warm-up requirement is usually
met in the course of meeting the Brief Procedures prerequisites listed above.)

Characteristic Description
Overvoltage Category Terminals on this product may have different installation (overvoltage) category
designations. The installation categories are:
CAT III DistributionĆlevel mains (usually permanently connected). Equipment at this
level is typically in a fixed industrial location.
CAT II LocalĆlevel mains (wall sockets). Equipment at this level includes
appliances, portable tools, and similar products. Equipment is usually
cordĆconnected.
CAT I Secondary (signal level) or battery operated circuits of electronic equipment.
Pollution Degree A measure of the contaminates that could occur in the environment around and within
a product. Typically the internal environment inside a product is considered to be the
same as the external. Products should be used only in the environment for which they
are rated.
Pollution Degree 1 No pollution or only dry, nonconductive pollution occurs.
Products in this category are generally encapsulated,
hermetically sealed, or located in clean rooms.
Pollution Degree 2 Normally only dry, nonconductive pollution occurs.
Occasionally a temporary conductivity that is caused by
condensation must be expected. This location is a
typical office/home environment. Temporary
condensation occurs only when the product is out of
service.
Pollution Degree 3 Conductive pollution, or dry, nonconductive pollution that
becomes conductive due to condensation. These are
sheltered locations where neither temperature nor
humidity is controlled. The area is protected from direct
sunshine, rain, or direct wind.
Pollution Degree 4 Pollution that generates persistent conductivity through
conductive dust, rain, or snow. Typical outdoor locations.
